Topic and Main Idea

Identifying Topics, Main Ideas, and Supporting Details

Understanding the topic, the gist, or the larger conceptual framework of a textbook chapter, an article, a paragraph, a sentence or a passage is a sophisticated reading task. Being able to draw conclusions, evaluate, and critically interpret articles or chapters is important for overall comprehension in college reading. Textbook chapters, articles, paragraphs, sentences, or passages all have topics and main ideas. The topic is the broad, general theme or message. It is what some call the subject. The main idea is the “key concept” being expressed. Details, major and minor, support the main idea by telling how, what, when, where, why, how much, or how many. Locating the topic, main idea, and supporting details helps you understand the point(s) the writer is attempting to express. Identifying the relationship between these will increase your comprehension.
